The working principle of vertical roller mill
1, the main structure and function
Roller is the main material for vertical roller mill parts. Mill built with two pairs of roller, each pair of rollers mounted on the same shaft, rotating at different speeds.
Disc fixed to the reducer output shaft, the upper part of the disc material bed, the bed material a circular groove.
PRM-type separator mainly composed of vertical roller mill, roller, disc, compression device, reducer, motor, housing and other components.
Fineness of separation is an important component of the decision, which consists of adjustable speed drives, rotor, guide blades, housing, meals, fighting off the cone material, composed of the outlet, and the separator works similar.
Pressure device is called the grinding pressure of the components provided by the high pressure oil station, hydraulic cylinder, rod, storage and other components, able to exert enough pressure roller grinding of materials.
2, the working principle of vertical roller mill
The material flow through the separator, in the role of guide vanes and the rotor, the coarse material to the disc from the hopper cone, the fine powder with a mill with air, dust collection device in the system to collect, is the product, the material in the contact process with the gas being dried to the required product water, by adjusting the angle and the wind guide vane separator rotor speed can be different fineness of the product.
Motor through reducer drive the disc rotation, the current hot air from the air inlet into the vertical roller mill, the material from the feed opening falls on the central disc; the centrifugal force, material to the disc edge and moved across the ring groove on the disc by the grinding roll compacted and crushed, to the edge of the disc moving through the air with the wind at the beginning and large particles fall back directly on the disc re-grinding.
Compared with the ball mill, vertical roller mill with the following features;
Compared with the cement ball mill vertical mill to the advantage is obvious, in order to establish a more intuitive description of the characteristics of MPS vertical mill, following the annual output of 10 tons of cement and production of raw material preparation system, for example, compared with the two HRM vertical roller mill and ball mill kinds of program indicators.
Grinding efficiency; drying large capacity; into the grinding material Liaodu large, medium and large vertical mill can save two broken; products, chemical stability; stars are homogeneous gradation, product Liaoduo uniformity is conducive to burning ; process is simple; low noise, less dust, the operating environment clean; metal loss, high utilization; use of the economy.

Rumble Roller 31 x 6 $69.99 RumbleRoller contains 200 specially designed "bumps". The bumps are firm, but flexible, much like the thumbs of a massage therapist. Conventional foam rollers have smooth, hard surfaces that further compress soft tissue. Rolling on top of foam rollers improves blood flow and tissue flexibility, but the effect is limited and relatively superficial, unless you spend a lot of time rolling.But, the Rumble Roller continuously kneads the contours of your body, gently stretching soft tissue (muscle and fascia) in multiple directions. Erodes trigger points, helps restore flexibility, and brings relief to common types of muscular pain. RumbleRoller's bumps are firmer than muscle tissue, but much softer than bone, so they deflect out of the way if they contact your spine or other bony protrusions. Guaranteed to outlast and outperform any foam roller that you've ever tried.Waterproof and latex free. Anti microbial additive that stops the growth of bacteria.Through simple techniques, you can control the amount of pressure the bumps apply to your body. The bumps are closely spaced to one another (< 2" apart), so several of them simultaneously contact your body during most exercises. However, with a slight shift of your body, you can reduce your area of contact with the RumbleRoller, which increases pressure and provides deeper, more penetrating relief. |
